I think that most of the people here are adults, well-intentioned, and many are very well educated.
To presume that the mods and even those posting here have not been down (ed. for misspelling) this conversation path would be off mark. We've been here before--oh, yes, many a time.
I think the majority of women here are also well-experienced in the ways of this naughty world, and while the advice to program in 112, remove oneself, and avoid laughing are all good bits of advice--the reality is that each woman or group of women will react a bit differently.
In the situation, which is not well practiced, different responses will kick in.
Just as in Leon, when a man who was following me and my companions--in fact, I had sternly admonished one to STOP conversing with him and WALK quickly on--seized me by both shoulders and moved in for a kiss.
My response was to shove him so hard with both hands on his shoulders that he flew backwards. Flew. Then, I walked on. One just never knows what the right response will be, and while a mental rehearsing is helpful, it is not muscle memory.
As most online, I'm a mature adult and have also (sadly) been in these situations many times, although with a few years on me, seem to be losing my supreme appeal! (a side benefit of maturity).
